  As shown in FIG. 1, the pressing tool 20 is composed of a bent plate body made of a single metal or the like, and has a pressing plate portion 21 that is curved slightly upward on the upper surface, and in the longitudinal direction of the pressing plate portion 21. The pressing leg piece 23 is provided with an opening 22 intermittently, extends downward from both ends in the width direction of the pressing plate portion 21 on the lower surface, and bends and protrudes in a stepped manner so as to narrow the space between the lower end plate pieces. It has a configuration with.

  The pressing tool 20 in this example has two openings 22 and 22, and a pressing operation portion 21 a is formed at a portion of the pressing plate portion 21 excluding the openings 22 and 22.

  The pressing tool 20 is preferably formed in various lengths corresponding to the width dimension of the heat shield sheet 10 to be used, and the opening 22 formed in the tool has a length of the pressing tool 20. An appropriate number of openings 22 may be provided depending on the dimensions.

  In this example, the opening 22 is formed by cutting a part from the end in the width direction of the plate. The opening 22 only needs to be formed with an insertion space and a placement space for the fixing member 61 that communicate at least from above to below.

  Further, of both leg portions 23b of the pressing leg piece 23, a fixing member 61 is provided at the bottom portion of the interior frame 50 described later at a portion located below the opening portion 22 of the leg portion 23b on the side where the opening portion 22 is not cut out. A notch 23c is formed on 51 so that it can be placed without touching the leg 23b (see FIG. 1B and FIG. 4 described later). In FIG. 1A, the arrangement state of the fixing member 61 is indicated by a two-dot chain line.

  In the present embodiment, as will be described later, the central step portion 23a and the leg portion 23b of the pressing leg piece 23 constitute a pressing portion that presses the interior frame 50 from above. As shown in FIG. 1C, the central step portion 23a is intermittently formed on the side where the opening 22 is cut out, and is continuously formed in the longitudinal direction on the side where the opening 22 is not cut.

  Further, a gap is formed between the plate pieces of the leg portion 23b of the pressing leg piece 23, and the width dimension of the leg portion 23b is formed smaller than the opening width of the groove portion 51 of the interior frame 50 described later.

  Details of how to use the pressing tool 20 will be described in detail with reference to FIGS.

  On the other hand, the heat shield sheet 10 is attached to the corrugated roof 1 as shown in FIG. 2, and the rooftop fixture 3 is fixed to the connecting mountain portion 1 a connecting the end portions of the roof material of the corrugated roof 1. In addition, the groove-shaped frame 30 is erected thereon, and the heat shield sheet 10 is further attached thereon. In addition, the roof of attachment object is not limited to the corrugated roof 1, A roof of another shape may be sufficient.

  Although the details of the structure of the on-roof fixture 3 are not shown in the drawing, two clamping pieces 3a are combined, and two on the shaft portion of the connecting bolt body 2 protruding above the connecting peak portion 1a. The sandwiching piece 3a is sandwiched and fixed to the roof. The grooved frame 30 is structured to be fixed to the roof fixture 3 with screws. 2 is a tightening bolt for tightening the two sandwiching pieces 3a to the shaft portion of the bolt body 2, and 1b is a roof material support fitting (tight) for fixing with the bolt body 2. Frame).

  About the roof fixture 3, you may use the roof fixture of another structure. In addition, in the case of a roof in which the roof material is joined to the roof, a roof fixture that can be fixed to the roof portion is used, but the present invention is also applicable to those using such a roof fixture. It is.

  The groove-shaped frame 30 for fixing the heat shield sheet 10 is formed of a concave groove body made of metal or a hard synthetic resin (for example, FRP), and is wound around both end portions in the width direction of the opening of the groove portion 31. The reinforced lip portion 34 is formed.

  In order to fix and stretch the heat shield sheet 10 on the roof, in addition to the groove-shaped frame 30, an interior frame 50 having substantially the same cross section as the groove-shaped frame 30, and a rectangular shape with rounded corners. The fixing member 61, the long wave spring 62, and the frame cover 40 that closes the opening of the groove 31 are used. At both ends in the width direction of the frame cover 40, pressing pieces 41 for pressing the heat shield sheet 10 are formed. The frame cover 40 is fixed by passing the bottom portion 32 of the channel frame 30 and the top plate portion of the rooftop fixture 3 with screws S.

  The heat shield sheet 10 is sandwiched between the outer surface of the interior frame 50 and the groove inner surface of the grooved frame 30 in the groove of the grooved frame 30 as described above, so that the heat shield sheet 10 does not shift from the inside of the groove. 61 and a wave spring 62 are pressed and fixed.

  Because of such a sandwiching structure, the interior frame 50 to be installed in the groove portion 31 of the groove-shaped frame 30 can have its bottom portion 52 extended in the width direction and bent along the longitudinal direction, and an open flange piece. It is desirable that the concave groove shape is not deformed so that 54 does not come off from the reinforcing lip portion 34 of the groove-shaped frame 30. For example, if an interior frame 50 is used that is made of a hard synthetic resin and has a plurality of staggered kerfs in the longitudinal direction at the bottom 52 so as to extend in the width direction and bend along the longitudinal direction. Good.

  On the other hand, the heat shield sheet 10 is made of a synthetic resin sheet that has flexibility and stretchability and reflects and blocks / insulates solar heat. For example, as shown in this embodiment, the heat shield sheet 10 reflects solar heat and the like. A fabric sheet formed by knitting a resin yarn material colored in silver or the like that cuts off and heat shields in length and breadth can be suitably used.

  The heat shield sheet 10 is fixed to a groove-shaped frame 30 fixed on the roof, and is stretched between the groove-shaped frames 30. In the present embodiment, the heat shield sheet 10 that is long in a band shape in a direction orthogonal to the grooved frame 30 is used. In addition, as shown in FIG. 3, the heat shield sheet 10 used in the present embodiment has a portion excluding both end portions 11 and 11 in the width direction (portions indicated by cross hatching) knitted with vertical and horizontal resin yarn materials. However, at both ends, the resin yarn material (weft 10a) is not fixed with the warp 10b (see a partially enlarged plan view surrounded by a one-dot chain line in FIG. 3).

  Next, a procedure for fixing and fixing the heat shield sheet 10 will be described with reference to FIGS.

  First, as shown in FIGS. 4 and 5, the leg portion 23 b of the pressing leg piece 23 of the pressing tool 20 is inserted into the groove portion 51 of the interior frame 50 to prepare for mounting on the channel frame 30. As described above, the insertion of the pressing leg piece 23 into the interior frame 50 is a loose fit due to the relationship between the width of the opening of the leg portion 23b of the pressing leg piece 23 and the groove 51 of the interior frame 50. The opening flange piece 54 of the frame 50 may be held with fingers so that both members are not removed.

  In this state, the pressing tool 20 is pressed into the groove of the grooved frame 30 while the bottom 52 of the interior frame 50 is deformed in a state where the heat shield sheet 10 is disposed on the opening of the groove 31 of the grooved frame 30. Then push it in (see FIGS. 4 to 6).

  The pressing operation portion 21 a of the pressing plate portion 21 of the pressing tool 20 in a state where the leg portion 23 b of the pressing leg piece 23 of the heat shielding sheet 10, the interior frame 50 and the pressing tool 20 is pressed into the groove portion 31 of the grooved frame 30. Is held by fingers so that the heat shield sheet 10 is not displaced, and the fixing member 61 is dropped from the opening 22 in this state (see FIG. 6).

  In the lower part of the pressing tool 20, a drop space for the fixing member 61 is formed in the one leg portion 23b by the opening 22, and a notch portion 23c is formed in the other leg portion 23b. In addition, the inner frame 50 can be smoothly placed on the bottom 52.

  Thus, according to this pressing tool 20, since the pressing plate portion 21 is formed on the upper surface and the pressing leg piece 23 is formed on the lower surface, the pressing plate is combined with the pressing frame 20 in the interior frame 50. The inner frame 50 can be easily attached to the groove-shaped frame 30 together with the heat shield sheet 10 simply by pressing into the groove 31 of the groove-shaped frame 30 while being pressed by the portion 21.

  Further, since the pressing tool 20 includes the opening 22 intermittently in the longitudinal direction of the pressing plate portion 21, the opening 22 can be used as an operation window for mounting the fixing member 61. Therefore, the fixing member 61 can be mounted in the groove without removing the pressing tool 20 after the interior frame 50 is fitted into the groove-shaped frame 30. After the interior frame 50 is pushed into the groove, it is only necessary to press the pressing plate portion 21 so that the heat shield sheet 10 is not displaced, so that the work can be performed easily.

  In particular, according to the pressing tool 20 of the present embodiment, since it is integrally formed with a single bent plate body, it can be manufactured by a simple manufacturing process without requiring a welding or fixing process in manufacturing. In addition, since the upper portion of the example shown in the figure is formed in a substantially square shape having a hollow upper portion, it is easy to grasp with fingers and particularly work.

  In the illustrated example of the present embodiment, the tip of the leg portion 23b of the pressing leg piece 23 is not in contact with the bottom 52 of the interior frame 50. 52 is deformed so as to protrude upward, and the leg 23b presses so that the deformed bottom 52 is not further deformed. In addition, you may form the leg part 23b still longer so that the bottom part 52 may not protrude upwards. Even in this case, since the notch 23c is formed, the fixing member 61 can be placed on the bottom 52 as shown in FIG. 1A without any problem.

  The heat shield sheet 10 attached to the grooved frame 30 as described above is fixed to the grooved frame 30 so as not to be displaced by mounting the fixing member 61 described below into the groove.

  The fixing member 61 is made of a substantially rectangular flat plate made of synthetic resin or metal, and an operation groove 61a along the long side direction is formed at the center thereof. The operation groove 61a is preferably a through groove so that it can be used on both sides.

  Further, it is desirable that the dimension of the long side of the fixing member 61 is a dimension that can press the side wall 33 of the groove portion 31 of the grooved frame 30 at both short sides.

  First, such a fixing member 61 is dropped into a groove in which the heat shield sheet 10 is mounted together with the interior frame 50 as described above, and is disposed along the longitudinal direction of the groove-shaped frame 30 (FIGS. 6 and 6). 7).

  In this state, the rotation operation piece 4a is inserted into the operation groove 61a of the fixing member 61 placed in the groove toward the lower side of the rotation operation piece 4a of the L-shaped saddle driver 4, and the fixing member 61 is inserted in the inserted state. Both short sides are rotated until they press against the side wall 53 of the interior frame 50 in the groove (see FIGS. 7 and 8).

  Since the fixing member 61 has a structure in which both short sides press the side wall 53 of the interior frame 50 in the groove (the side wall 33 of the grooved frame 30), until the long side is orthogonal to the longitudinal direction of the grooved frame 30. By rotating, the fixing member 61 is press-fitted. As a result, the heat shield sheet 10 is sandwiched between the groove inner surface of the grooved frame 30 and the outer surface of the interior frame 50 and fixed.

  By attaching a plurality of such fixing members 61 in the width direction of the heat shield sheet 10, the heat shield sheet 10 is fixed to the groove portion 31 of the grooved frame 30 so as to be hardly displaced.

  Since the pressing tool 20 of this example includes two openings 22, the fixing member 61 can be attached at two locations without moving the pressing tool 20. Since the pressing tool 20 does not need to be moved, the pressed state can be maintained, and the heat shield sheet 10 can be prevented from being loosened during work. Note that only one opening 22 may be provided. In that case, the pressing tool 20 may be slid in the longitudinal direction of the grooved frame 30 to move the opening 22 to another position.

  After the heat shield sheet 10 is temporarily fixed in this way, the wave spring 62 is further mounted in the groove 31 so that the side wall 33 of the groove 31 is pressed from the inside by the peak 62a and the valley 62b (see FIG. 9). .

  In the state where the elastic force before the interior does not act, the wave spring 62 has a width dimension (twice the amplitude) from the peak portion 62a to the valley portion 62b larger than the width dimension (inner dimension) of the bottom portion 32 of the groove portion 31. It is formed and elastically deforms by being installed in the groove portion 31, and an elastic return force acts to further press the inner frame 50 toward the side wall 33 of the groove portion 31.

  After the heat shield sheet 10 is fixed to the groove-shaped frame 30 by pressing from the inside of the groove portion 31 in this way, the frame cover 40 is covered so as to hide the opening of the groove portion 31, and is grooved with screws S (drill screws or the like). It fixes to the shape frame 30 (refer FIG. 9).

  Next, a second embodiment of the present invention will be described.

  FIGS. 10A, 10 </ b> B, 10 </ b> C, and 10 </ b> D are a plan view, a front view, a bottom view, and a side view, respectively, of a heat shield sheet pressing tool according to the second embodiment.

  The pressing tool 20 shown in the present embodiment is formed by joining two identically shaped plate bodies 20a and 20a made of L-shaped metal in a side view and one of the two plate bodies 20a and 20a on the upper surface. It has a pressing plate portion 21 in which the pieces are connected to each other, and has openings 22 and 22 intermittently in the longitudinal direction of the pressing plate portion 21, and the other pieces of the two plate bodies 20 a and 20 a on the lower surface. It is the structure provided with the pressing leg piece 23 which overlaps. The other pieces are connected by caulking, but may be joined by bolts, nuts, welding, or the like.

  The pressing tool 20 in this example has two openings 22 and 22, and a pressing operation portion 21 a is formed at a portion of the pressing plate portion 21 excluding the openings 22 and 22.

  The pressing tool 20 is preferably formed in various lengths corresponding to the width dimension of the heat shield sheet 10 to be used, and the opening 22 formed in the tool is formed of the pressing tool 20. An appropriate number of openings 22 may be provided according to the length dimension.

  In the illustrated example, the opening 22 is formed by cutting out a part from the end of the other piece of each plate to the center in the width direction of the one piece. The opening 22 only needs to have an insertion space for the fixing member 61 that communicates at least from above to below.

  Further, as shown in FIG. 10 (d), the pressing plate portion 21 is formed so that the one piece is substantially flush with each other. The lower surface portion 21b of the pressing plate portion 21 constitutes a pressing portion that presses an opening flange piece 54 of the interior frame 50 described later from above.

  On the other hand, the pressing leg piece 23 is formed to have a width dimension smaller than the opening width of the groove portion 51 of the interior frame 50 described later. As will be described later, this pressing leg piece 23 also constitutes a pressing portion for pressing the bottom portion 52 of the interior frame 50.

  The corrugated roof and the on-roof fixing tool to be attached to the heat shield sheet 10 used in the present embodiment are the same as those shown in the first embodiment, and thus illustration and description thereof are omitted. Moreover, the heat shield sheet 10 is the same as that of the first embodiment, and the description of the detailed structure is omitted.

  Further, the mounting structure of the groove-shaped frame 30 and the heat shield sheet 10 to the groove-shaped frame 30 is the same as that shown in the first embodiment, and illustration and description thereof will be omitted (FIG. 2 of the first embodiment, (See FIG. 3).

  Next, a procedure for pressing the heat shield sheet 10 into the grooved frame 30 in the procedure for fixing the heat shield sheet 10 will be described with reference to FIGS. 11 to 13. In addition, since the fixing procedure to the groove-shaped frame 30 by the fixing member 61 and the attachment procedure of the frame cover 40 are the same as those of the first embodiment in the fixing and tensioning procedure of the heat shield sheet 10, illustration and description are omitted ( (Refer FIG. 7-9 of 1st Embodiment).

  First, as shown in FIGS. 11 and 12, the pressing leg piece 23 of the pressing tool 20 is inserted into the groove 51 of the interior frame 50 to prepare for mounting on the grooved frame 30. As described above, the insertion of the pressing leg piece 23 into the interior frame 50 is a loose-fitting state due to the width dimension of the opening of the groove portion 51 of the pressing leg piece 23 and the interior frame 50. It is only necessary to hold the flange piece 54 with fingers so that both members do not come off.

  In this state, the pressing tool 20 is grooved while the bottom portion 52 of the interior frame 50 is pressed and deformed at the tip of the pressing leg piece 23 with the heat shield sheet 10 disposed on the opening of the groove portion 31 of the grooved frame 30. It pushes in the groove | channel of the shape frame 30, and pushes in (refer FIGS. 11-13).

  Thus, also in this embodiment, since the pressing plate part 21 is formed in the upper surface and the pressing leg piece 23 is formed in the lower surface, the pressing tool 20 is in a state where the pressing leg piece 23 is attached to the interior frame 50. The inner frame 50 can be easily attached to the grooved frame 30 together with the heat shield sheet 10 by simply pressing the pressing plate 21 into the groove 31 of the grooved frame 30 while pressing the pressing plate 21 with a finger.

  Further, since the lower surface portion 21b of the pressing plate portion 21 that is the base portion of the pressing leg piece 23 is configured to hold the opening flange piece 54 of the interior frame 50, after the interior frame 50 is mounted in the groove of the channel frame 30, It is sufficient that the pressing plate portion 21 is pressed so that the heat shield sheet 10 is not displaced, so that the work can be performed easily.

  Further, since the pressing tool 20 includes the opening 22 intermittently in the longitudinal direction of the pressing plate portion 21, the opening 22 can be used as an operation window for mounting the fixing member 61. Therefore, the fixing member 61 can be mounted in the groove without removing the pressing tool 20 after the interior frame 50 is fitted into the groove-shaped frame 30. During the work, it is only necessary to press the pressing plate portion 21 so that the heat shield sheet 10 is not displaced, so that the work can be performed easily.

  In particular, according to the pressing tool 20 of the present embodiment, since the two pieces of the L-shaped plate are fixed to each other, manufacturing can be performed easily and rapidly. If two L-shaped members having the same shape are formed in combination, it is not necessary to increase the number of components, which is convenient in terms of component management. Further, in the example shown in the figure, since the pressing plate portion 21 is formed by connecting one wide piece of L-shaped plate pieces, the pressing plate portion 21 can be formed wide and the pressing operation can be easily performed. .
